20090274221 | METHOD, HARDWARE PRODUCT, AND COMPUTER PROGRAM PRODUCT FOR PERFORMING HIGH DATA RATE WIRELESS TRANSMISSION - A method, a hardware product, and a computer program product for performing high data rate wireless transmission and reception. Minimum shift-keyed (MSK) data is transmitted by multiplexing a first MSK data stream and a second MSK data stream wherein the first MSK data stream is substantially 90-degree phase-shifted with respect to the second MSK data stream. The transmitted MSK data is received by performing phase recovery and demodulation using an FM discriminator having a demodulation circuit for implementing a 45-degree phase shift prior to demodulation. | 11-05-2009 |
20090319706 | TRANSMITTING PARALLEL DATA VIA HIGH-SPEED SERIAL INTERCONNECTION - Synchronized pseudo-random number outputs are produced at a transmitter and a receiver of a high-speed serial interconnection. At the transmitter, using logic XOR operations, each data word of parallel data is selectively scrambled with one of the pseudo-random numbers and transmitted via a high-speed serial interface. The receiver de-scrambles the received serial data stream and restores the parallel data. | 12-24-2009 |
20110145675 | CALCULATION TECHNIQUE FOR SUM-PRODUCT DECODING METHOD (BELIEF PROPAGATION METHOD) BASED ON SCALING OF INPUT LOG-LIKELIHOOD RATIO BY NOISE VARIANCE - One or more embodiments provide a decoding technique (and its approximate decoding technique) enabling a stable operation even if a noise variance is low at the implementation with a fixed-point arithmetic operation having a finite dynamic range. A technique is provided for causing a computer to perform calculation using a sum-product decoding method (belief propagation method) with respect to LDPC or turbo codes. For calculating an update equation of a log extrinsic value ratio from an input, a (separated) correction term is prepared obtained by variable transformation (scale transformation) of the update equation so that the update equation is represented by a sum (combination) of a plurality of terms by transformation of the equation and a communication channel noise variance is a term separated from other terms constituting a sum of a plurality of terms as a term to be a factor (scale factor) by which a log is multiplied. With an estimated communication channel noise variance as an input, the (separated) correction term is approximated by a simple function so as to cause the computer to make calculation (iteration) on the basis of a fixed point on bit strings of finite length (m,f: m is the total number of bits and f is the number of bits allocated to the fractional part). | 06-16-2011 |
